Hey all, trying to sort out an issue for a freind.... ve series 2 sv6..... replaced the dual mass with a single mass..... they cannot get the clutch to disengage... He had a crack at bleeding it.... I have since redone it.... doesnt appear to have any more air and the pedal feels good.... you can start the car with it in gear clutch in but cant select gears once running..... someone mentioned to me that there should be a spacer to modify between single and dual mass..... any thoughts?
